Romelu Lukaku has revealed Inter Milan spotted an issue with his digestive system soon after he completed a transfer from Manchester United.

Lukaku, in an interview with ESPN, revealed that Inter's nutritionists spotted an irregularity that has now been sorted and resulted in his losing 10 pounds in the space of 12 days shortly after he'd joined the Italian club.

The former United striker came under fire for his fitness and professionalism towards the end of last season, with Gary Neville particularly critical.

Lukaku has since hit back, instructing Neville to "never question my professionalism" and has hit ground running for Inter under Antonio Conte. After a number of goals in pre-season after the deadline day move from United, the Belgian has hit two in two in Serie A this season — and one for Belgium in their Euro 2020 qualifying win over Scotland.
